A new CNN Poll of Polls in Colorado suggests the battle for the state's 9 electoral votes is a dead heat. In the survey, compiled Sunday, 47 percent of likely voters in Colorado back Barack Obama for president, with 46 percent supporting John McCain. Seven percent of those questioned are undecided.

The CNN Poll of Polls is a compilation of the latest surveys in the state. The polls in this latest average are a Mason-Dixon survey conducted September 29-October 1, a CNN/Time/Opinion Research Corporation poll taken September 21-23, and an American Research Group survey conducted September 23-25.

Both campaigns are spending a lot of time and money campaigning in Colorado. McCain made a swing through the state on Thursday and Friday. Obama last campaigned in Colorado on September 29. The Democrats also held their party's national convention there in late August.

Colorado, New Mexico, and Nevada are three mountain west states that voted for George W. Bush in 2004 that the Democrats are hoping to turn from red to blue come Election Day.

Sen. Obama campaigned in Pennsylvania Friday where he currently holds a 10-point lead over Sen. McCain, according to a new CNN Pennsylvania poll of polls.

(CNN) – A day after the McCain campaign announced that it is shifting resources out of Michigan and into other battleground states, CNN’s latest polls of polls in New Hampshire and Pennsylvania suggest that Sen. John McCain may face an uphill battle in both states between now and Election Day.

Sen. Barack Obama is now ahead in New Hampshire by 6 percentage points. Obama has the support of 48 percent of likely voters in New Hampshire while McCain’s support stands at 42 percent and 10 percent are unsure about their choice for president.

In CNN’s previous New Hampshire poll of polls released on September 26, Obama was up by two points – 46 percent to McCain’s 44 percent.

During the Democratic primaries, Obama lost Pennsylvania to Sen. Hillary Clinton. In CNN’s latest poll of polls, however, Obama leads McCain by 10 percentage points with likely Pennsylvania voters – 51 percent versus 41 percent, with 8 percent unsure. In CNN’s previous Pennsylvania poll of polls released on October 1, Obama also led McCain by 10 points – 49 percent to 39 percent.

(CNN) – As the fate of the first head-to-head debate between Sen. Barack Obama and Sen. John McCain remains uncertain, CNN’s latest poll of polls shows the Democratic nominee with a 4 point advantage over his Republican rival. Obama has the support of 47 percent of voters to McCain's 43 percent, with and 10 percent unsure about their choice for president. In CNN’s previous poll of polls, released Wednesday night, Obama was ahead by 5 points – 49 percent versus 44 percent.

“Since the start of the financial crisis, Sen. Obama has held a small but clear edge in the horserace,” said CNN Senior Political Researcher Alan Silverleib. “Sen. McCain’s decision to suspend his campaign in the midst of this crisis can be seen as an attempt to regain the upper hand on the economy — an issue which so far continues to work to Obama’s advantage. The overwhelming majority of Americans are more concerned with the state of the economy than with any other issue.”

Thursday’s national general election poll of polls is comprised of the following four surveys: Marist (September 22-23), Fox News/Opinion Dynamics (September 22-23), Gallup (September 22-24), and Diageo/Hotline (September 22-24). CNN’s poll of polls does not have a sampling error.

Sens. McCain and Obama put politics aside recently to come together and observe the 7th anniversary of the 9/11 attacks at Ground Zero.

(CNN) – The race for the White House remains virtually neck-and-neck, according to CNN’s latest poll of polls.

For the first time since September 7, Sen. Barack Obama is ahead of Sen. John McCain in CNN’s national poll of polls. Obama has the support of 46 percent of registered voters compared to 45 percent for McCain, while nine percent are unsure about their choice for president. In Tuesday’s CNN poll of polls, the two men were tied at 46 percent each.

“The presidential race has been a virtual dead heat since the end of the conventions,” noted CNN Senior Political Researcher Alan Silverleib. “At the moment, the McCain and Obama campaigns’ advertising strategies appear to be cancelling each other out. What we can’t yet measure, however, is the impact of the crisis on Wall Street. Economic issues favor Obama, but voters tend to support McCain more in terms of overall leadership and crisis management. The bottom line is that, with 48 days to go, this race is a toss-up.”

Wednesday’s poll of polls is comprised of the following four national general election surveys: IPSOS-McClatchy (September 11-15), Gallup (September 14-16), Diageo/Hotline (September 14-16), and American Research Group (September 13-15). The poll of polls does not have a sampling error.

(CNN) - Saturday’s CNN national Poll of Polls - which includes the new Newsweek survey - shows McCain leading Obama by one point (46 to 45 percent). Friday’s Poll of Polls showed McCain leading Obama by two points (46 to 44 percent).

The national general election "Poll of Polls" consists of four surveys: Newsweek (September 10-11), Fox News/Opinion Dynamics (September 8-9), Gallup (September 9-11), and Diageo/Hotline (September 9-11). The Poll of Polls does not have a sampling error.

(CNN) – Sen. John McCain continues to have a slight advantage over rival Sen. Barack Obama in the latest CNN poll of polls released Friday afternoon. McCain is now ahead by 2 percentage points – 46 percent to Obama’s 44 percent - with 10 percent unsure about their choice for president. In Thursday’s CNN poll of polls, McCain was ahead by one point – 46 percent to 45 percent.

“The race for the White House has essentially been a dead heat since the Republican Convention,” noted CNN Senior Political Researcher Alan Silverleib. “Barring something dramatic and unexpected, the horserace numbers are not likely to change very much at least until the debates. As we inch closer to Election Day, the pool of truly undecided voters continues to shrink.”

Friday’s CNN poll of polls is comprised of the following three surveys: Fox News/Opinion Dynamics (September 8-9), Gallup (September 9-11), and Diageo/Hotline (September 9-11). The poll of polls does not have a sampling error.

In Wednesday’s Poll of polls, McCain’s margin over Obama is one point, with McCain at 46 percent, Obama at 45 percent and 9 percent unsure about their choice for president.

In Tuesday’s poll of polls, the two rivals were also separated by just one point, with McCain at 47 percent and Obama at 46 percent.

"Why is the race so close? The GOP convention energized the Republican base - but it also helped solidify Democratic opposition to the GOP ticket,” CNN Polling Director Keating Holland said. “Enthusiasm grew among Democrats and Republicans after the Republican convention. Also, the favorable ratings for Obama and McCain are almost identical - and virtually unchanged from where they were in mid-August, before either party's convention began."

Wednesday’s poll of polls is composed of the following five national general election surveys: Fox News/Opinion Dynamics (September 8-9), NBC/Wall Street Journal (September 6-8), American Research Group (September 6-8), Gallup (September 7-9), and Diageo/Hotline (September 7-9).

(CNN) - John McCain’s edge is growing in the latest CNN Poll of polls - the first comprised of surveys conducted entirely after the Republican convention.

After averaging in new survey results from CBS, ABC/Washington Post, and Gallup, CNN’s national Poll of polls now shows McCain leading Obama by 2 points, 47 to 45 percent. The CNN Poll of polls released earlier Monday showed McCain ahead of Obama by 1 point, 47 to 46 percent. Eight percent are undecided.

“John McCain is riding high after an extremely successful Republican Convention,” said CNN Senior Political Researcher Alan Silverleib. “For the first time all year, McCain is ahead of Obama in the Poll of Polls. The GOP base is energized. The so-called ‘convention bounce’ is alive and well, and has resulted in an overall swing of seven percentage points in McCain’s favor since the Republicans met in St. Paul on September 1. This historic race for the White House will now likely remain tight all the way to Election Day.”

The national general election "Poll of Polls" consists of five surveys: CNN (September 5-7), ABC/Washington Post (September 5-7), CBS (September 5-7), Gallup (September 5-7), and Diageo/Hotline (September 5-7). The Poll of Polls does not have a sampling error.

Sens. McCain and Obama appeared briefly on stage together last month during a forum moderated by Pastor Rick Warren at the Saddleback Church in California.

(CNN) - Sen. Barack Obama’s lead in national polls has shrunk to one point, according to CNN’s latest “poll of polls.”

Sunday’s poll of polls shows Obama leading John McCain 44 to 43 percent.

Obama held a three-point lead in Saturday’s poll of polls. The senator from Illinois was leading McCain 45-42 percent.

"All of the surveys included in our national polling average were conducted at least in part during the Republican Convention," noted CNN Senior Political Researcher Alan Silverleib. "It's still too early to know exactly how much of a bounce McCain has received. That said, the daily tracking numbers indicate that the [Sarah] Palin pick has clearly energized the GOP's base. We have an extremely tight race for the White House on our hands."

CNN’s most recent poll of polls consists of three surveys: CBS (September 1-3), Gallup (September 4-6), and Diageo/Hotline (September 2-4). The poll of polls does not have a sampling error.

The Republican convention took place last week in St. Paul, Minnesota. Democrats held their convention during the last week of August in Denver, Colorado.

(CNN) - Barack Obama holds a six point lead over John McCain in the latest CNN poll of polls.

The poll of polls, an average of five recent national surveys, shows the Illinois senator at 49 percent among registered voters nationwide with McCain at 43 percent.

“When you average the latest national polls, Obama appears to be slowly expanding his lead. He was ahead by four points before the Democratic Convention, and now he’s up by six,” noted CNN Senior Political Researcher Alan Silverleib.

“That said, we’ve seen swings of a point or two on a regular basis over the couple of months. The jury is still out on whether Obama will benefit from any sustained convention bounce. We’re also still waiting to see what — if any — impact the Palin pick and the Republican Convention will have on the race.”
